Using the emlxdrv Utility
The emlxdrv utility is intended to be used for binding (associating) the Emulex emlxs (Leadville Fibre
Channel) driver and the Emulex lpfc (traditional non-Leadville Fibre Channel) driver to the various
models of Emulex Fibre Channel HBAs. This allows both drivers to coexist in the same host and attach
to mutually exclusive Emulex Fibre Channel HBA models. In other words, the emlxs driver can be
configured to attach and operate one set of HBA models, while the lpfc driver can be configured to
attach and operate a different set of HBA models. However, Solaris does not allow both drivers to attach
and operate the same model of HBA even if there are multiple HBAs of that model present. If the driver
binding configuration is changed, the host system must usually be rebooted in order for the new
configuration to take effect.
Modes of Operation (emlxdrv)
The emlxdrv utility program can be run in two modes:
• Interactive
• CLI
Interactive Mode (emlxdrv)
Run the emlxdrv utility program in interactive mode by typing the name of the program without any
command line arguments:
# emlxdrv
After it is started, the emlxdrv program scans the host system and prepares a driver configuration table
consisting of bindings (associations) between the emlxs and lpfc drivers and a list of Emulex Fibre
Channel HBA models. After the table is prepared, the utility displays the following:
